Inventor: MIRKIN CHAD A
IPC: A61K47/48
Filed: 1999-11-30
Abstract: The invention provides a method of preparing nanoparticles having at least one polymer shell attached to them, each polymer shell having a selected property or properties. The method comprises attaching initiation monomers to the surfaces of the nanoparticles, contacting the nanoparticles having the initiation monomers attached to them with a transition metal ring-opening metathesis catalyst to activate the initiation monomers, and contacting the nanoparticles with one or more types of propagation monomers of the formula P-L-N under conditions effective so that the monomers are polymerized to form the one or more polymer shells. In the formula P-L-N, N is a cyclic olefin-containing group, P is a moiety which gives each polymer shell a selected property or properties, and L is a bond or linker. The invention also provides polymers formed by polymerizing the propagation monomers. The invention further provides the nanoparticles, the initiation monomers, and propagation monomers of formula P-L-N wherein P  is a moiety having a property selected from the group consisting of redox activity, optical activity, electrical activity and magnetic activity, and L and N are defined above. The invention also provides binding monomers of formula B-L-N, wherein B is a binding moiety that binds specifically to an analyte, and N and L are defined above.

Patent CA-2355087-A1 (CA)
Inventor: PAYRAUDEAU MICHELE
IPC: C02F3/30
Filed: 1999-12-17
Abstract: A single tank submerged membrane bioreactor for treating feed water having unacceptable levels of ammonia or total nitrogen has both a membrane scouring bubble supply and an oxygenating bubble supply. The membrane scouring bubble supply continuously provides large scouring bubbles to clean the membranes.  Permeate is continuously withdrawn from the membranes at a high rate but the large scouring bubbles do not transfer sufficient oxygen to the mixed liquor to create aerobic conditions in the reactor. The oxygenating bubble supply is operated to provide small bubbles of air or oxygen that intermittently produce aerobic conditions in a significant part of the mixed liquor. Alternating aerobic and anoxic conditions occur in a significant portion of the tank suitable for nitrification and denitrification. The level of dissolved oxygen (DO) or oxygen reduction potential (ORP) in the tank is measured by sensors and determines when the oxygenating bubble supply will be turned on or off between set minimum and maximum time limits.

Abstract: Selon l'invention, on produit une transglutaminase possédant une activité enzymatique en soumettant une transglutaminase à l'état dénaturé à un procédé comprenant au moins les étapes suivantes (a) et (b) consistant: (a) à former une structure intermédiaire - possédant l'activité enzymatique dans un milieu aqueux, dans des conditions acides - de l'enzyme dénaturée, pendant la formation de la structure, et (b) à former une structure d'ordre supérieur - possédant l'activité enzymatique dans un milieu aqueux à une valeur de pH se situant dans la région neuronale - de l'enzyme possédant la structure intermédiaire, pendant la formation de la structure, comme décrit ci-dessus. Ainsi, la transglutaminase obtenue à l'état dénaturé (par exemple, une transglutaminase produite par un micro-organisme de recombinaison de gène) peut subir une renaturation efficace, ce qui permet donc de produire industriellement une transglutaminase extrêmement pure, possédant une activité enzymatique sensiblement comparable à l'activité de la transglutaminase authentique (c'est-à-dire l'activité de transglutaminase). L'intermédiaire possède la structure intermédiaire pendant la formation de la structure, comme décrit ci-dessus.

Title: System and method for initializing a simple network management protocol (snmp) agent
Inventor: YOST WILLIAM HENRY
IPC: H04L29/06
Filed: 2000-09-22
Abstract: A system and method for initializing an SNMP agent in SNMPv3 mode. In one aspect of the invention, a method is provided that allows an operator to securely enter the initial SNMPv3 privacy and authentication keys into an SNMPv3 device and cause the device to enter in SNMPv3 mode. The SNMP manager and SNMP agent both generate an associated random number and public value (steps 100, 101, 200, 201). The SNMP manager passes its public value to the SNMP agent in a configuration file, which causes a proprietary MIB element in the SNMPv3 device to be set with the public value of the SNMP manager (steps 202, 104). The SNMP manager reads the public value of the SNMP agent through an SNMP request using an initial valid user having access to the public value of the SNMP agent (steps 103, 203). The SNMP agent and SNMP manager each independently compute a shared secret using the Diffie-Hellman key exchange protocol (steps 105, 204). The SNMP manager and SNMP agent each independently convert the shared secret into the same readable password (steps 106, 205), convert the readable password into the same secret key (steps 107, 206) and set the initial authentication key and the initial privacy key to the value of the secret key (steps 108, 207).
